Abstract

Built-in sink with a waste opening which is adjoined downwardly by a drop shaft terminating above a waste bin. The latter is guided in horizontal guide rails supported by a holding device which is attached to the underside of the built-in sink and also supports the drop shaft. In order to eliminate cleaning of the latter, there is inserted into the waste opening from above a removable protective shaft which is closable by a removable cover.
